OpenJewelry, No Pliers Required

They say that if you want something done right, you gotta do it yourself. Oftentimes, that goes double for getting something done at all. Whereas some people might simply lament the lack of a (stable) Thingiverse-type site for, say, jewelry designs, those people aren’t Hackaday’s own [Adam Zeloof]. With nowhere to share designs among engineering-oriented friends, [Adam] took the initiative and created OpenJewelry, a site for posting open-source jewelry and wearable art designs as well as knowledge about techniques, materials, and processes.

[Adam] has seeded the site with a handful of his own beautiful designs, which run the gamut from traditional silversmithing techniques to 3D printing to fancy PCBs with working blinkenlights. You really should check it out, and definitely consider contributing.

Even if you don’t have any jewelry designs to share, the code is open as well, or you could even edit the wiki. Just be sure to read through the contribution guidelines first. If you don’t have the time for any of that, donations are welcome as well to help maintain the site.

We love wearable art around here, especially when it serves another purpose like this UV-sensing talisman, or this air quality necklace.

How to cast rings

Casting Engagement Rings (Or Other Small Metal Parts!)

[Paul Williams] wrote in to tell us about his most recent and dangerous endeavor. Marriage.

As a masters student in Mechanical Engineering, he wanted to give his wife (to be) to be a completely unique engagement ring — but as you can imagine, custom engagement rings aren’t cheap. So he decided to learn how to make it himself.

During the learning process he kept good notes and has produced a most excellent Instructable explaining the entire process — How to make the tools you’ll need, using different techniques and common problems you might have. He even describes in detail how to make your own mini-kiln (complete with PID control), a vacuum chamber, a wax injector and even the process of centrifugal casting.
